But we don't have anything like FF as an alternative to go from Android. Especially considering banks require "certified OS".
The last one applies in my country. You can of course go to the bank branch for every little financial operation, which is bad enough by itself for us living in cities, but is practically impossible for my relatives in the rural area, who would have to drive 100 km to the nearest bank branch, and then back just to move some money between two accounts.
Even if you don't care for anyone else but your country, it will come to you also, I promise.
Forcing you to use foreign megacorps for essential services should be illegal if not already.
The only realistic thing left for me is moaning about it on the ole 'net and hoping (probably in vain) that this disease doesn't spread further to other countries. Western democracies are already in the process of copying several bad ideas we implemented 10+ years ago (and China more than 20 years ago), I don't see a reason why this also wouldn't be ported over.
And the digital sovereignty argument doesn't really work, one of the banks uses its own payment system — mostly copied from Chinese AliPay — and it's the most popular one here. Zero dependence on "the West" other than the phones themselves, where they think they have an alternative in Huawei and friends, and you're gonna have to depend on someone in any case, even just for internet infrastructure, or even cash printing machines.
